l snrcrne MACHINE.

Application led July 18, 1928. Serial No. 293,633.

My invention relates to a slicing machine which will be light, simple to manufacture, eliicient, any easy to operate. One purpose of my invention is the provision of a slicing machine ofthe type described, wherein a particularly accurate adjustment of the gauge.

Another object is the provision of means for f moving the gauge plate angularly toward and away from the knife and for preventing lmovement of the gauge plate when adjusted.

' Other objects will appear from time to time in the co'urse of the specification and claims.

I illustrate my invention .more or less diagrammatically in the accompanying drawings, wherein- Figure l is a plan view With parts in horizontal section, andparts in skeleton outline; Figure 2 is a section on the line 2-2 of Figure l;

Figure 3 is a section on the line 3-3 of Figure 2; T

Figure 4 is a view similar to Figure l of a portion of the device With the gauge plate Withdrawn from the cutting plane of the knife; and

Figure 5 is a section on the line 5 5 of Figure 1.

Like? parts are indicated by like symbols throughout the specification and drawings. A generally indicates any suitable base frame` or member. VMounted upon it is any suitable motor means, herein shown as the 4o motor B, from which projects the motor shaft B1 on which is the driving pulley B2 adapted to engage and drive the belt B3 which enters the channel B4 of the pulley B2.

C generally indicates the upwardly pro- 45 jet-ting housing or frame member which includes the shieldvportion C1 and the knife l supporting sleeve C2.

`Mounted Within the sleeve Czvis the knife 'shaft and assembly generally indicated as D which includes the knife shaft proper D1 as- 50 sociated with which is the pulley D2 about which passes the belt B1.

E is a knife disc secured to the enlarged end portion D3 of the shaft D1. It is shown as convex andy is peripherally cut away or re- `cessed on its hollow face as at lE8 tov leave a peripheral projection Et. It is recessed in its rear face as at E5 to receive the shield E".

vG. is a ti'aclnlherein shown as of circular cross-section, mounted for example on the l supports G1vupwardly projecting from the opposite ends of the base A. Aligned beneath the track G is any suitable slide or rail G2, herein shown as of rectangular crosssection.

Moimted for movement along the track G and the rail G2 is any suitable carriage or supporting member H, herein shown as carrying the face plate member II1 whereby the meat may be advanced along the carriage toward the cutting plane of the knife.

I generally indicates a face plate adjustably and removably mounted upon a supporting member I1 as by the screws I2. The face plate supporting member I1 is mounted upon or integral with the laterally and rearwardly extending member which includes the vertically spaced walls I3 I4. Depending from and secured to the bottom wall I4 is a depending portion I5 on which is mounted the Worm engaging rack or gear I8. I'I I8 are bearing 80 members associating with or depending from the member I.

Mounted on the base A. beneath the member I4 is a shaft K one end of Which rotates in the bearing lug K1, herein shown as integral with the frame and the other in a bushing K2 mounted in the frame as `by the *screw K1. The shaft K passes through the bearings I" I8 and therefore serves as a track along which moves the face plate supporting structure above described. K4 indicates a spiral or worm gear held against movement in relation to the shaft K and meshing with therack I". It w ill be understood that rotation of the shaft K moves the gauge plate and gauge plate supporting assembly along a path parallel with the axis of said shaft.

In order to rotate said shaft I provide th thrust ball L5, also mounted in the bushing K2. It will be understood that the engagement of the abutments L2 L3 limits the ro-` tation of the shaft K and the worm K4 in one direction, thus setting out the outward limit of movement of the face plate.

The aperture L4 is so positioned as to serve as a lock, in association with the ball L5, at the inner limit of the movement of the face plate, a lock which requires the application of extra force to the knob to release the knob for adjusting the face plate.

In order to maintain a tension on the worm I provide a spring M, herein shown as a tensional spring, one end being mounted to the abutment M1 secured to the member I8 and the other being mounted to the abutment 4M2 which is held in position by the screw K3.

In order to balance or adjust the member I* and thus the face late-itself I provide the adjusting members O1 which project upwardly against the bottom of the member I4. They are controlled by the adjusting screws O2 and the nuts O3. l

It will be realized that whereas I have described and shown a practical and operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative and .diagrammatic rather than as limiting me to my specific showing.

The use and operation of my invention are as follows:

I provide a method or form of gauge plate adjustment which is an improvement on that shown in my co-pending application No. 259,163, filed on March 5, 1928. In my present form the gauge plate is adjustably mounted upon a supporting member, as by the screws I2 and it will be understood that the gauge plato may be removed from its support or may be adjusted vertically or horizontallyto some slight extent or may be tilted in its vertical plane, this result being obtained by having some slight clearance between the supporting screws or bolts I2 and the apertures in the member I1 through which they pass, as indicated in Figure 2.

The gauge plate assembly includes the bottom wall I4 which projects rearwardly horizontally from the member I1. The shaft K serves as a track to support the face plate assembly and to guide it along the desired path,

path of movement, since rotationof the shaft K actually moves the gauge plate assembly, the worm K4 meshing with the gear I6. In order to prevent rattling and to maintain a constant working engagement between the` opposed worm and gear or rack I provide the spring member M. The opposed abutments L2 L3 serve to limit the outward movement of the gauge plate, and the engagement of the aperture L4 and the ball L5 serve as a locking means to hold the gauge plate at its innermost position'when it is left in such position.`
